WINDING MECHANISM.

Specification of Letters Patent. Patgnted A 25 19 22 Application filedNovember 12, 1920. SerialNo. 423,700.

To all whom it may concern:

Be it known that I, GEORGES E. HENRY, a citizen of Switzerland, residingat Mansfield, in the county of Richland and State of Ohio,have inventedcertain new and useful Improvements in Winding Mechanisms, of which thefollowing is a specification.

My invention relates to a winding orrewinding" device and has particularapplication to spring motors and the like and es-' pecially to thatparticular class of apparatus known as trolley retrievers and trol- Tothe attainment of these ends and the accomplishment of other new anduseful obejcts, the invention consists in the novel features ofconstruction, combination and relation of the various parts to behereinafter more fully described and claimed, and shown in theaccompanying drawings and in which Y Y Fig. l is a side view in sectionof my device attached to a spring motor for controlling a trolley polerope and with the handle in a lowered or inoperative position and thedevlce out of engagement with the mechanism of the spring motor.

Fig.2 is aside view in section as in Fig. l but thehandle in operativeposition and the device in engagement with the spring -1n'otor parts.

Fig.3 is a view on line. 33 of Fig.1.

Fig. 4 is-a view on line M'ofFig. 2/

Fig. 5 is an expanded view of those-parts of my: device'contained withinthe case and difficult to show clearly incother views.

This figure alsoshows the relation of-the partswhen in operative andinoperative'position. I

' In describing the preferred form of my invention, I will; forsimplicity, showit as attached to a trolley rope tender-for merelycontrolling theslack in a trolley rope'by Numeral 1 represents thebackof the case and the cover by any convenient well known means (notshown). A shaft-3 is shown as secured to the case 1 at the back end, andthe front end is enlarged to form a hub to better support the cover. 2.A reel 5 is mounted ,on the shaft and has a projection 6 to which issecured one end of a spring7 at the'points' 8. The other end of thespring is secured to the case at 9.- A trolley rope 10 is secured-to thereel and the other endof the rope to a trolley pole. To the front faceof the reel is secured a ratchet wheel 11 having teeth 12 as bettershown in Fig, 5. To the inner face of the cover is a circular boss 13and mounted on the boss is a reciprocating plate 14:, (:Fig. 3 and Fig.5 which has a projecting clevis 15 which pro-. jects through a slot 16inthe: cover. The plate 14: is permitted to rotate back and forth throughthe angle formed by the lines is represented by 2 which. is secured. to1 ACBO, or in other words is limited only by the extent of openingof theslot 16. To the projecting clevis 15 is pivoted a-handle 17 at'the point18 and in such manner that it can be raised or lowered, as shown byFlgs. 1 and 2, about the pivotal point 18 and when in a closed orinoperative position as in Fig. 1 it is held in that position by "thespring latch 19 en gaging the handle through the opening 20. Anyconvenient and obvious means may be used to maintainv the handle asinFig. 1 as I am not claiming .anyspecific means. Atthe pivotal end ofthe handle isa lug 21 adapted'to engage a shifting plate 22- (SeefFig.5') and raise it when the handle is lowered or to disengage the plate 14when the handle is raised and permit the plate 22 tolower.

' Secured to'the reciprocating plate 14 is a pawl 23 constantlyyurgedbackward" by :a spring 24. This'pawl has a projecting stud 25 whichprojects through a slot 26 in the reciprocating. plate without engagingwith the plate and also projects'through a slot 27 in the shiftingplate" 22 and engages the lower end of the slot 27 and held thereby thespring 24:. This-engagementof the pawl 23- and'pla-te 22 tends to raiseand lower the free end of the pawl about the point 28 asa and 4 the pawlis in engagement with the ratchet wheel. Asthe reciprocating plate 14 ismoved back and forth the pawl moves back and forth with it due to itsbeing piv oted to the plate at the point 28 and since the pawl isyieldingly held in coacting engagement with the ratchet wheel it willtend to engage and re-engage the ratchet wheel when the plate 14 ismovedio-rward and back through the medium of the handle 17. The relativeposition of the reciprocating and shifting plates and pawl and ratchetwheel is better shown by Fig. 5, Y and Z,

.when the parts are in operative position to handle is moved so as tomove the ratchet wheel in the direction E of the arrow, the pawl 80 willmaintain the ratchet wheel against rotation of the wheel in the reverseor D direction by the spring 7. The pawl 23 might be termed the rotatingpawl and the pawl 30 the holding pawl.

The shifting plate 22 is held in position bythe slot 38, thesides ofwhich engage the boss 13 on the cover but permit an upward and downwardmovement. The plate 22 is further held in place by the channel 34 in.

the rear face of the'plate 14. V

The operation of the device above de scribed and shown by the drawingsis as follows :-Upon raising the handle 17 the shifting plate 22 is freeto drop through the ac-' tion of gravity and springs 24 and 32. Thispermits pawls 23 and 30 to engage the ratchet wheel 11. The handle isnow reciprocated which imparts a forward and backward movement to thepawl 23 and as the handle is moved forward the ratchetwheel is rotatedin the direction E of the'arrow and an amount proportional to theforward movementof the handle, and this movement is further imparted tothe reel and spring 7 to wind the same. Upon moving the handle in thebackward direction the'pawl 23 'is' permitted to ratchet over the teethl2'by the spring 24 and the pawl 30,engaging the ratchet wheelpreventsthe wheelmoving backward with'the backward movementof the pawl 23, undera force exerted by the spring 7. This backward and forward motion of thehandleiis continued until the spring 7 has been wound to the desiredamount. One end of the rope'is then secured to the reel and the otherend to the trolley pole or other device or to the reelonly as desired.Upon returning the handle to its normal or inoperative position theshifting plate 22 is moved upwardby the engagement of the projection 21with the shifting plate 22 and this moves the two pawls out ofengagement with the ratchet wheel, thereby allowing the reel to properlyfunction under action of the spring 7 upon the rope.

I have shown my winding, rewinding or tensioning device as attached tothe simplest form of spring motor, merely a spring secured to a reelfortaking slack out of a trolley rope, to avoid complicating drawings,but it is equally adapted to be asso ciated with other forms of springmotor such as trolley retrievers, motor starters, fishing reels, etc.,where it is desiredto alter the tension of the spring. My device is alsoadapted to be used as a winding mechanism, without any reference'to aspring; for instance, merely to wind-a rope on a reel and it can beputtomany uses obvious to'one skilled in the art and the device shownand described herein permits of many varieties and I do not wish to belimited in the scope of my invention other than by the appended claims.1
